Claims (1)

수신된 변조신호를 기저대역으로 천이시키고 I 및 Q성분수신신호로 분리하는 주파수변환 과정과, 상기 주파수변환과정에서 분리된 기저대역의 I 및 Q성분수신신호를 소정주기로 양자화하고 양자화된 I 및 Q성분수신신호를 부호화하여 I 및 Q성분수신데이터를, 발생하는 A/D변환과정과, 상기 A/D변환과정에서 발생된 I 및 Q성분수신데이터와 기준파형데이터간의 상관관계를 검사하고, 상기 상관관게 검사결과에 의하여 위상편차를 검출하며 상기 검출된 위상편차에 대하여 단위샘플구간당 변화량을 검출하는 위상편차검출과정과, 상기 위상편차검출과정에서 검출된 단위샘플구간당 위상편차를 상기 A/D변환과정에서 발생된 I 및 Q성분 수신데이터에 대해 매 샘플마다 역으로 보상하는 위상편차 보상과정을 포함함을 특징으로하는 위상편차검출 및 보상방법.A frequency conversion process of shifting the received modulation signal to the baseband and separating the I and Q component reception signals, and quantizing the baseband I and Q component reception signals separated in the frequency conversion at predetermined intervals and quantizing the I and Q components. The I / Q component reception data is generated by encoding the component reception signal, and the correlation between the I / Q component reception data generated in the A / D conversion process and the reference waveform data is examined. The phase deviation detection process detects the phase deviation based on the correlation test result and detects the amount of change per unit sample interval with respect to the detected phase deviation, and the A / D conversion of the phase deviation per unit sample interval detected in the phase deviation detection process. Phase deviation detection and compensation method, characterized in that it comprises a phase deviation compensation process for inversely compensating for each sample I and Q component received data generated in the process . ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
